1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundWe tested whether tissue-based analysis of p53 and PTEN genomic status in primary tumors is predictive for subsequent sensitivity to abiraterone and enzalutamide in castration-resistant prostate cancer (CRPC).

methodsWe performed a retrospective analysis of 309 consecutive patients with CRPC treated with abiraterone or enzalutamide. Of these, 101 men (33%) had available primary tumor tissue for analysis. We screened for deleterious TP53 missense mutations and PTEN deletions using genetically validated immunohistochemical assays for nuclear accumulation of p53 protein and PTEN protein loss, with sequencing confirmation of TP53 mutations in a subset. Overall survival (OS) and progression-free survival (PFS) were compared between patients with and without p53 and/or PTEN alterations.

resultsForty-eight percent of the evaluable cases had PTEN loss and 27% had p53 nuclear accumulation. OS and PFS did not differ according to PTEN status, but were significantly associated with p53 status. Median OS was 16.7 months (95% CI, 14-21.9 months) and 31.2 months (95% CI, 24.5-43.4) for men with and without p53 nuclear accumulation, respectively (HR 2.32; 95% CI 1.19-4.51; P = 0.0018). Similarly, median PFS was 5.5 months (95% CI, 3.2-9.9 months) and 10.9 months (95% CI, 8-15.2 months) in men with and without p53 nuclear accumulation, respectively (HR 2.14, 95%CI 1.20-3.81; P = 0.0008). In multivariable analyses, p53 status was independently associated with PFS (HR 2.15; 95% CI 1.03-4.49; P = 0.04) and a HR of 2.19 for OS (95% CI 0.89-5.40; P = 0.087).

conclusionsp53 inactivation in the primary tumor (but not PTEN loss) may be predictive of inferior outcomes to novel hormonal therapies in CRPC.
